Multi-purpose lots

I wish they would not limit us to one classification category when defining lot types. By that, I mean why can't a lot be both a gym and a retail store for example? I want to have a gym but also sell workout clothes and protein bars. Or a retail/ residential lot? Or a restaurant/pool lot where you could eat and swim like at a cabana club? Maybe you want a bakery and a cafe, where people can buy cupcakes but also order coffee.

Please let us have the option to add a second category to the lot designation, this will expand a ton of gameplay possibilities but also help a ton with the limited space issue.
